Class ANGLETextureUsage

In some implementations it is advantageous to know the expected usage of a texture before the backing storage for it is allocated. This can help to
inform the implementation's choice of format and type of memory used for the allocation. If the usage is not known in advance, the implementation
essentially has to make a guess as to how it will be used. If it is later proven wrong, it may need to perform costly re-allocations and/or
reformatting of the texture data, resulting in reduced performance.

This extension adds a texture usage flag that is specified via the TEXTURE_USAGE_ANGLE TexParameter. This can be used to indicate that the application
knows that this texture will be used for rendering.

Field Summary

Accepted as a value to param for the TexParameter{if} and to params for the TexParameter{if}v commands with a pname of
TEXTURE_USAGE_ANGLE; returned as possible values for data when GetTexParameter{if}v is queried with a value of TEXTURE_USAGE_ANGLE.

GL_FRAMEBUFFER_ATTACHMENT_ANGLE

public static final int GL_FRAMEBUFFER_ATTACHMENT_ANGLE

Accepted as a value to param for the TexParameter{if} and to params for the TexParameter{if}v commands with a pname of
TEXTURE_USAGE_ANGLE; returned as possible values for data when GetTexParameter{if}v is queried with a value of TEXTURE_USAGE_ANGLE.
